The dealership has received about a hundred emails -- mostly positive and a few negative -- in response to the ad.

Stuart Gaffney and John Lewis, who are leaders in Marriage Equality USA, remember when a national furniture ad featuring a gay couple was pulled in 1994 when someone threatened violence.

The Toyota ad shows America has become more tolerant toward same-sex couples, Gaffney and Lewis said.

"That's why we are seeing majority support nationwide for freedom to marry," Gaffney said. "People realize we are part of every community part of every family. Business support is a part of that change."
